Yes, a bead roller can do the job.I like a hand swadge machine. Both machines however can cause difficulty in keeping the object round, especially with small diameters,such as 3" and 4" round diameter.

It's slightly elliptical when you roll it, because it is stretched out of material at a perpendicular angle. It will grow uneven especially around the double seam, so grow it from the center one way then double back to finish. If you're fitting a pipe inside the end of another pipe, like in a downspout drain, you add to the elliptical angle relative to the decrease in the top to bottom. Your pattern ends up like an arc shape.
